Open-source FE software for truss analysis

What's the best open source FE code for nonlinear transient analysis of truss structures (preferably with Python interface)?

Educational iPad app on structural mechanics

I would like to share with fellow mechanicians an educational iPad app I recently developed. The name of the app is Truss Me! and the main goal is to help students, all the way from high school to college, to build intuition on how truss structures behave. The video below highlights some features of the app:

Pin problem in Abaqus.

Hi
I have a quite (i think) easy problem to solve. Its a truss bar problem that is connected with pins where I just need to investigate the displacment(u).
(its a triangle with a bar in the middle, upper chord is planar and the middle bar is vertical.)

My problem is just that i have never used any pin function in abaqus.

Mechanics in the news

Since I am an alum of the University of Minnesota, when I was a PhD student I lived only a few blocks from the site of yesterday's catastrophic bridge collapse in Minneapolis.  The statics analysis of a truss is almost the first thing learned by every undergraduate engineering student, and appears to be relevant here.  It is interesting to see words like "fatigue crack" and "vibrations" in the news .  In light of such events,
